The Daily Grind: What abilities do you find the most fun to use?

Hitting 51 on my Scoundrel in Star Wars: The Old Republic meant getting what is probably the greatest ability ever, the ability to quickly roll forward. I absolutely love any sort of quick movement ability like that, especially rolls -- anything that lets me dart around the battlefield without being directly tied to combat. Being able to do so in Guild Wars 2 was one of my favorite parts of the game as a whole.

We've all got certain abilities that we just like making use of in MMOs. Sometimes they're not really beneficial to our builds, and sometimes they're not even all that useful, but darn it they're just plain fun to trigger. So what abilities do you find the most fun to use? Silly cosmetic tricks? Certain impressive storms of particle effects? Or are you just fond of abilities that work well from a mechanical standpoint with no concern for silly elements?
